SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to realize an excellent engagement mechanism, and can preserve a noise degree remarkably reduced than conventional roller chains.
SC form silent chains may be utilized for large pace and substantial tension transmission much like a toothed metallic belt because the 
plates immediately engage with all the sprockets for driving.
SCR-04 silent chains are made with inner engaging framework for even further decreased noise degree.
PS silent chain
A PS kind silent chain has a framework in which a set of specially formed connecting pins and locker pins make contact with just about every other whilst rotating at each flexible bearing place. As a result, it generates less heat especially in substantial speed operation and is outstanding in durability. On top of that, the specially formed pins greatly reduce shock once the chain is engaged with sprockets, providing a larger silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth types to the SCA 04××, SC 25××, SC 06×× about the former webpage and PS silent chains to ensure silent substantial pace operation. For all sizes, the sprocket tooth heads are frequently hardened by induction hardening or carburizing.
